Animation Images file name

Hi. Using Rhino 7, 7.10.21256.17002. (Mac)
In recording animation, how does one control the name of the image files created? It’s common to use those images as a video in Adobe Premier. Premier requires a simple chronological naming convention, such as “001.png, 002.png” etc.
My files are now named per the ID of the reference curve used in the path animation (ie: path_2006.png).

Thanks for the help!
